Earpiece documentation

What Earpiece is

Earpiece is a real-time interview copilot. It listens to your interviewer, transcribes the question, and instantly shows you a sharp, spoken-ready answer in your own voice, on your screen, kept out of the screen-share. It works for research and behavioral interviews, AI-training and data-annotation screens, and live coding rounds.

It runs in your browser on any device, and as an invisible desktop app on Windows for the strongest screen-share protection.

Get started

1. Sign in. Enter your email on the homepage and we email you a secure sign-in link, no password to remember.
2. Set your profile. Open Setup and paste your résumé or a short description of who you are. Earpiece answers as you. See Profiles.
3. Add this interview's context. In the This interview box, drop the study, role, or company notes for the session.
4. Start an interview and pick how Earpiece should listen. See below.

Sign in & your account

How signing in works

There's no password. You enter your email and we email you a 6-digit code (and a one-tap link). Type the code, and you're in. The code is single-use and expires in 15 minutes.

One account, every device

You use the same account on the web app, the desktop app, and your phone. You sign in once on each device (each keeps you logged in afterwards). Everything important is stored on the account, so it follows you:

• Your profiles (résumé / personas)
• Your plan and billing
• Your interview count for the day

So set up your profile once on the web, and it's already there when you open the desktop app.

Managing your account

Open the account menu (top-right of the app) to see your plan, Manage subscription (change card, cancel), upgrade, log out, or delete your account. Cancelling keeps your access until the end of the period you already paid for.

Which setup should I use?

Earpiece can run a few ways. Pick by where your call is and where you want to read the answers.

If you want to… do this

• …be invisible even when sharing your whole screen → install the desktop app and use it.
• …read answers on your phone while the call's on your PC → pair your phone (Max). Your phone shows the answers and never uses a mic.
• …keep answers off your main screen on a normal call → use the Float window and share only a tab/window (not the whole screen).
• …answer in another language → set the language before you start.
• …have it answer as a specific persona → switch the active profile.

Running an interview

An interview is an explicit session you start and end. It keeps your usage tidy and is the unit your plan counts.

1. Tap Start interview. The context you entered is attached to that session.
2. Choose how to listen: PC / system audio (best), the desktop app, or phone / mic. See Capture modes.
3. When the interviewer finishes a question, the answer appears. Glance, say it in your words. Use Answer now to force one, or Regenerate / Shorter / Rephrase to adjust.
4. Tap End interview when you're done.

Capture modes

How Earpiece hears the interviewer. Pick the cleanest one available to you.

PC / system audio recommended

Click Start · PC/system audio, then share the call's browser tab with “Share tab audio” ticked, or Entire screen with system audio for a desktop app like Zoom or Teams. This captures only the computer's audio, never your microphone, so it never mistakes your reply for a new question.

Phone / mic

On a phone, the mic listens to the interviewer played on your speaker. Keep the room quiet and the phone near the speaker.

Phone as the screen you read on

The best use of a phone is the paired viewer: the computer captures the audio and your phone shows the answers. The phone never uses its microphone, so it never hears you.

Desktop app (install & use)

The desktop app is the strongest option: its window is removed from screen capture by the operating system, so it's invisible even when you share your entire screen. Get it from the download page.

Install on Windows

1. Download Earpiece-Setup.exe and run it.
2. It isn't code-signed yet, so Windows may say “Windows protected your PC.” Click More info → Run anyway. (This is normal for a new app.)
3. It installs and opens. If the installer's “run” step shows a small error, just open Earpiece from the Start menu.

Install on macOS

1. Download the right .dmg, Apple Silicon (M1-M4) or Intel.
2. Open it and drag Earpiece to Applications.
3. First launch only: right-click the app → Open → Open (Gatekeeper blocks unsigned apps from a normal double-click).
4. Grant Screen Recording and Microphone when macOS asks (System Settings → Privacy & Security). Screen Recording is what lets it capture the call's audio.

Using it

• Sign in with your email + code (same account as the web).
• Start an interview and choose system audio, on the desktop app there's no “share your screen” picker; it grabs the call audio directly.
• Ctrl/Cmd + Shift + \ instantly hides or shows the window. On macOS, Cmd + Shift + Q quits.

Answer modes

Switch with one tap to reshape how Earpiece answers.

Profiles & résumé

Your profile is who Earpiece answers as, your background, tools, and a few honest opinions. It's stored on your account and follows you across devices.

• Upload résumé (PDF, DOCX, or text) and Earpiece turns it into a tight first-person profile.
• Keep multiple profiles (e.g. different personas or roles) and switch the active one before an interview.
• The This interview box is separate, per-session notes about the specific study, role, or company.

Float window

The Float button pops your question and answer into a small always-on-top window. When you share a single tab or window, that floating window is a different surface, so it isn't in the shared view. Chromium desktop browsers (Chrome, Edge, Brave) only.

Hear answers in your earbud

The most natural way to use Earpiece: instead of reading the answer, have it spoken into your earbud. You listen, then say it in your own words with your eyes on the camera, no looking down, no reading tone. It runs entirely on your device (nothing is sent anywhere) and starts the moment the answer streams.

1. In the answer area, tap 🎧 Speak: Off to turn it On.
2. Pick a voice and speed (a little faster keeps it ahead of you).
3. Wear a wireless earbud so only you hear it.

Pair your phone Max

The cleanest setup when your call is on a computer but you'd rather read on your phone. Your computer captures the interviewer from system audio and mirrors the question and answer to your phone. No microphone is used anywhere, so it never hears you, and the phone is never in the screen-share.

1. On the computer, start an interview and pick PC / system audio.
2. Tap Pair phone, it shows a 6-character code and a link.
3. On your phone, open that link (or go to /pair and enter the code).
4. Answers now appear on your phone in real time. Read there, glance up, and speak.

Languages & tuning

• Language: transcribe and answer in any of 12 languages, or auto-detect.
• Answer length: short, medium, or detailed.
• Sensitivity slider: how quiet a voice still registers. Slide up if it's missing the interviewer; down if room noise triggers it.
• Wait slider: how long a pause counts as “done talking” before Earpiece answers. Raise it if it cuts the interviewer off.

Watch the level bar while the interviewer talks to calibrate. Your settings are remembered.

Staying undetected

What's hidden depends on how you capture and what you share:

For full-screen shares (common in proctored tech screens), use the desktop app or the two-device method. On a phone there's no capture-exclusion API, so the phone is hidden only because it's a separate device.

Sounding natural

Modern interviews increasingly watch behavior, not just your screen, long pauses, eyes tracking text, a flat read. Earpiece can't be heard, but you can still give yourself away. Tips:

• Don't read it word-for-word. Glance, then say it in your own words.
• Use Shorter for a glanceable version on simple questions.
• Keep your eyes mostly on the camera; look down briefly, like you're thinking.
• Start talking before you've read the whole thing, natural speech has false starts.

Plans & billing

Payment: card or crypto everywhere; in Nigeria you can also pay in Naira (card, bank transfer, or USSD) at checkout. Card and Naira subscriptions renew monthly and cancel anytime from your account menu; crypto buys prepaid access in 1, 3, or 12-month blocks.

After paying, access activates automatically, card in seconds, crypto once it confirms on-chain.

Privacy & data

• Your interview answers are streamed live and never stored on our servers.
• Your profile is saved to your account so it follows you across devices; you can edit or delete it anytime.
• You can delete your account and data yourself from the account menu.

See the Privacy Policy and Terms.

Troubleshooting

It's not hearing the interviewer

Raise the Sensitivity slider, or switch to PC / system audio (much cleaner than a mic). On a phone, move it closer to the speaker and quiet the room.

It cuts the interviewer off / answers too early

Raise the Wait slider so a natural mid-question pause doesn't trigger an answer.

It types something when no one's talking

That's the speech model guessing from noise. Lower the Sensitivity slightly, or use system audio. Earpiece already filters common phantom phrases.

It picked up my own voice

Use PC system audio or the desktop app so it never hears you. In mic mode, keep auto-pause after each answer on.

“Share your screen” picker keeps appearing

That's the browser's way of granting system audio; only the audio is used and the video is dropped. The desktop app skips the picker entirely.

The answer looks generic

Set a profile so Earpiece answers as you. With no profile it stays general and won't invent a fake background.

FAQ

Getting started & account

Is it free to try? Yes, every account gets one free 10-minute trial interview (live listening time), then you pick a plan.

I didn't get my sign-in code. Check spam, wait a minute, and request again. Make sure the email is typed correctly. Each new code replaces the last.

Do I sign in separately on the app and the web? Yes, once per device, but it's the same account, and your profile, plan, and history carry across automatically.

Can I have more than one persona? Yes, keep multiple profiles and switch the active one before an interview.

Being seen / privacy

Will the interviewer see it on a screen-share? On a normal call: the desktop app is invisible even on a full-screen share; the Float window is hidden when you share a single tab or window; the paired-phone view isn't on your computer at all. On your own machine you still see everything.

Does it work on Zoom, Meet, Teams? Yes, the desktop app's invisibility is at the OS level, so it works the same across all of them. The web app captures the call's tab/system audio.

Will it hear my own voice? Not with system audio or the paired phone (no microphone involved). Only phone-mic mode can hear you, and it auto-pauses after each answer to avoid it.

Are my answers stored? No, answers are streamed live and never saved on our servers. Your profile is stored on your account so it follows you; you can delete it any time.

Will it work on a proctored test (lockdown browser, webcam, AI proctor)? No, and don't rely on it there. Those watch your camera and your machine, which no screen-hiding tool changes. Earpiece is for open, conversational, screen-share interviews. See Where it's safe vs not.

Plans & limits

How many interviews can I do? Earpiece Pro: up to 2 interviews per day. Earpiece Max: unlimited.

What's an “interview”? A session you start with the Start interview button. It carries that session's context and counts once toward your daily limit. Stopping and restarting capture within it doesn't count again.

What does Max add over Pro? Unlimited interviews, Coding mode, Coding-vision (read a problem off your screen), and phone pairing.

How do I pay? Card or crypto anywhere; in Nigeria you can also pay in Naira (card, bank transfer, or USSD) at checkout. Card/Naira renew monthly and cancel anytime; crypto buys 1, 3, or 12 months up front.

How do I cancel? Account menu → Manage subscription. You keep access until the end of the period you've paid for.

Desktop app

Why does it say “unknown publisher”? It isn't code-signed yet. It's safe, on Windows click More info → Run anyway; on macOS right-click → Open the first time.

Is there a Mac version? Yes, Apple Silicon and Intel builds on the download page.

The installer showed an error on “finish.” Harmless, just open Earpiece from the Start menu. The app installed fine.

Phone or tablet app? No native phone app, phones can't hide a window from screen capture. Use your phone as the paired viewer instead.

Using it well

It cuts the interviewer off / answers too early. Raise the Wait slider. It misses quiet audio? Raise Sensitivity, or use system audio. See Troubleshooting.

Answers sound generic. Set a profile so it answers as you.

Best tip? Don't read it word-for-word, glance, then say it in your own words. See Sounding natural.
